[Mad Reloader]

I remember that thread....

Also another one that Rocky Raab got in on, I think both he and I started taking calipers to .22 projectiles and comparing results.

Summing up those conclusions:

1) Quality products tend to perform better in most arms

2) Bullet diameter needs to match, or possibly exceed slightly, bore diameter. They're all lead bullets folks, and a slightly oversize projo will squinch down slightly. BUT YOU NEED OBTURATION. Worst results in his & my and the third guy's tests indicated an underzize projo for bore diameter, in all 3 instances.

3) Some arms really really prefer certain makes of .22 round. My INFAMOUS got-it-for-under-$50 .22 SA revolver from my longterm project in Heber AZ...seems to perform best with CCI, and of the CCI's...the REALLY cheap Blazers.

4) There's an oddball DEFINITELY subcaliber .22 out there that has the obturation problem licked...and in states such as WI (but definitely NOT Arizona!) has some application to very small game, at short ranges.

That would be the Hirtenberger & GeCo brand .22 CB caps. Propellant is a double dose of priming compound. Projo is essentially a miniature Minie ball, or a .22 skirted airgun pell without wasp waist.

These WILL function in any bore diameter of .22 LR rimfire out there.

They WON'T cycle an action.

They MAY have problems extracting, as the case is copper, not brass.

Wind drift is a MAJOR concern here.

BUT: On a windless day on the outskirts of Milwaukee or Wisconsin Dells or Madison, WI -- or in a home-made basement firng range with exhaust fan -- or if you want to actually fire that old ancient S&W #1 rimfire pistol and not have it self-destruct....it's "da kine."
